安装步骤

1. 下载安装ES对应Plugin Release版本

安装方式:

方式一

a. 下载对应的release安装包,最新release包可从baidu盘下载(链接:https://pan.baidu.com/s/1mFPNJXgiTPzZeqEjH_zifw 密码:i0o7)

b. 执行如下命令安装,其中PATH为插件包绝对路径:

./bin/elasticsearch-plugin install file://${PATH}

方式二

a. 使用elasticsearch插件脚本安装command如下:

./bin/elasticsearch-plugin install https://github.com/KennFalcon/elasticsearch-analysis-hanlp/releases/download/v6.5.4/elasticsearch-analysis-hanlp-6.5.4.zip

2. 安装数据包

release包中存放的为HanLP源码中默认的分词数据,若要下载完整版数据包,请查看HanLP Release

数据包目录:ES_HOME/plugins/analysis-hanlp

注:因原版数据包自定义词典部分文件名为中文,这里的hanlp.properties中已修改为英文,请对应修改文件名

3. 重启Elasticsearch

注:上述说明中的ES_HOME为自己的ES安装路径,需要绝对路径

4. 热更新

在本版本中,增加了词典热更新,修改步骤如下:

a. 在ES_HOME/plugins/analysis-hanlp/data/dictionary/custom目录中新增自定义词典

b. 修改hanlp.properties,修改CustomDictionaryPath,增加自定义词典配置

c. 等待1分钟后,词典自动加载

注:每个节点都需要做上述更改

提供的分词方式说明

hanlp: hanlp默认分词

hanlp_standard: 标准分词

hanlp_index: 索引分词

hanlp_nlp: NLP分词

hanlp_n_short: N-最短路分词

hanlp_dijkstra: 最短路分词

hanlp_crf: CRF分词(已有最新方式)

hanlp_speed: 极速词典分词

样例

POST http://localhost:9200/twitter2/_analyze
{
  "text": "美国阿拉斯加州发生8.0级地震",
  "tokenizer": "hanlp"
}
{
  "tokens" : [
    {
      "token" : "美国",
      "start_offset" : 0,
      "end_offset" : 2,
      "type" : "nsf",
      "position" : 0
    },
    {
      "token" : "阿拉斯加州",
      "start_offset" : 0,
      "end_offset" : 5,
      "type" : "nsf",
      "position" : 1
    },
    {
      "token" : "发生",
      "start_offset" : 0,
      "end_offset" : 2,
      "type" : "v",
      "position" : 2
    },
    {
      "token" : "8.0",
      "start_offset" : 0,
      "end_offset" : 3,
      "type" : "m",
      "position" : 3
    },
    {
      "token" : "级",
      "start_offset" : 0,
      "end_offset" : 1,
      "type" : "q",
      "position" : 4
    },
    {
      "token" : "地震",
      "start_offset" : 0,
      "end_offset" : 2,
      "type" : "n",
      "position" : 5
    }
  ]
}

远程词典配置

配置文件为ES_HOME/config/analysis-hanlp/hanlp-remote.xml

<properties>
    <comment>HanLP Analyzer 扩展配置</comment>

    <!--用户可以在这里配置远程扩展字典 -->
    <entry key="remote_ext_dict">words_location</entry>

    <!--用户可以在这里配置远程扩展停止词字典-->
    <entry key="remote_ext_stopwords">stop_words_location</entry>
</properties>

1. 远程扩展字典

其中words_location为URL或者URL+" "+词性,如:

1. http://localhost:8080/mydic

2. http://localhost:8080/mydic nt

第一个样例,是直接配置URL,词典内部每一行代表一个单词,格式遵从[单词] [词性A] [A的频次] [词性B] [B的频次] ... 如果不填词性则表示采用词典的默认词性n。

第二个样例,配置词典URL,同时配置该词典的默认词性nt,当然词典内部同样遵循[单词] [词性A] [A的频次] [词性B] [B的频次] ... 如果不配置词性,则采用默认词性nt。

2. 远程扩展停止词字典

其中stop_words_location为URL,如:

1. http://localhost:8080/mystopdic

样例直接配置URL,词典内部每一行代表一个单词,不需要配置词性和频次,换行符用 \n 即可。

注意,所有的词典URL是需要满足条件即可完成分词热更新:

  • 该 http 请求需要返回两个头部(header),一个是 Last-Modified,一个是 ETag,这两者都是字符串类型,只要有一个发生变化,该插件就会去抓取新的分词进而更新词库。

  • 可以配置多个字典路径,中间用英文分号;间隔

  • URL每隔1分钟访问一次

  • 保证词典编码UTF-8

自定义分词配置

HanLP在提供了各类分词方式的基础上,也提供了一系列的分词配置,分词插件也提供了相关的分词配置,我们可以在通过如下配置来自定义自己的分词器:

Config Elastic version
enable_custom_config 是否开启自定义配置
enable_index_mode 是否是索引分词
enable_number_quantifier_recognize 是否识别数字和量词
enable_custom_dictionary 是否加载用户词典
enable_translated_name_recognize 是否识别音译人名
enable_japanese_name_recognize 是否识别日本人名
enable_organization_recognize 是否识别机构
enable_place_recognize 是否识别地名
enable_name_recognize 是否识别中国人名
enable_traditional_chinese_mode 是否开启繁体中文
enable_stop_dictionary 是否启用停用词
enable_part_of_speech_tagging 是否开启词性标注
enable_remote_dict 是否开启远程词典
enable_normalization 是否执行字符正规化
enable_offset 是否计算偏移量

注意: 如果要采用如上配置配置自定义分词,需要设置enable_custom_config为true

例如:

PUT test
{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_hanlp_analyzer": {
          "tokenizer": "my_hanlp"
        }
      },
      "tokenizer": {
        "my_hanlp": {
          "type": "hanlp",
          "enable_stop_dictionary": true,
          "enable_custom_config": true
        }
      }
    }
  }
}
POST test/_analyze
{
  "text": "美国,|=阿拉斯加州发生8.0级地震",
  "analyzer": "my_hanlp_analyzer"
}

结果:

{
  "tokens" : [
    {
      "token" : "美国",
      "start_offset" : 0,
      "end_offset" : 2,
      "type" : "nsf",
      "position" : 0
    },
    {
      "token" : ",|=",
      "start_offset" : 0,
      "end_offset" : 3,
      "type" : "w",
      "position" : 1
    },
    {
      "token" : "阿拉斯加州",
      "start_offset" : 0,
      "end_offset" : 5,
      "type" : "nsf",
      "position" : 2
    },
    {
      "token" : "发生",
      "start_offset" : 0,
      "end_offset" : 2,
      "type" : "v",
      "position" : 3
    },
    {
      "token" : "8.0",
      "start_offset" : 0,
      "end_offset" : 3,
      "type" : "m",
      "position" : 4
    },
    {
      "token" : "级",
      "start_offset" : 0,
      "end_offset" : 1,
      "type" : "q",
      "position" : 5
    },
    {
      "token" : "地震",
      "start_offset" : 0,
      "end_offset" : 2,
      "type" : "n",
      "position" : 6
    }
  ]
}
